| + | ====== Let's Talk About Non-Volatile Memory Database Systems ====== | ||
| + | ==== Joy Arulraj, CMU ==== | ||

| + | ===== Abstract ===== | ||
| + | |||
| + | The advent of non-volatile memory (NVM) will fundamentally change the | ||
| + | dichotomy between memory and durable storage in database management | ||
| + | systems (DBMSs). These new NVM devices are almost as fast as DRAM, but | ||
| + | all writes to it are potentially persistent even after power loss. | ||
| + | Existing DBMSs are unable to take full advantage of this technology | ||
| + | because their internal architectures are predicated on the assumption | ||
| + | that memory is volatile. With NVM, many of the components of legacy | ||
| + | DBMSs are unnecessary and will degrade the performance of data | ||
| + | intensive applications. | ||
| + | |||
| + | In this talk, I will discuss our work in developing new high- | ||
| + | performance DBMSs that are able to take advantage of NVM's unique | ||
| + | properties. I will begin by discussing the development of different | ||
| + | storage and recovery methods for OLTP workloads. Our experimental | ||
| + | evaluation on a NVM hardware emulator show that these NVM-optimized | ||
| + | methods achieve up to 5.5X higher throughput than their traditional | ||
| + | counterparts while reducing the amount of wear due to write operations | ||
| + | by up to 2X. These methods are also able to restore the database to a | ||
| + | correct state nearly instantaneously after a crash. I will then | ||
| + | discuss the early development of N-Store, a new hybrid DBMS designed | ||
| + | specifically for NVM. | ||
| + | |||

| + | Joy Arulraj is a second year Ph.D. student in the Computer Science department | ||
| + | at CMU. He is advised by Prof. Andy Pavlo. His general research interest | ||
| + | is in database systems. Recently, he has been looking at exploiting | ||
| + | non-volatile memory technologies to improve the performance of database | ||
| + | systems. Before coming to CMU, Joy received is M.S. in Computer Science from | ||
| + | the University of Wisconsin, Madison and is B.E in Computer Science from | ||
| + | the College of Engineering, Guindy (Anna University). | ||
